Synthesis method of N, N-dimethyl-3-aminopropyltrimethoxysilane

The invention belongs to the field of production and manufacturing of silane coupling agents, and particularly discloses a synthesis method of N, N-dimethyl-3-aminopropyl trimethoxy silane. The N, N-dimethyl-3-aminopropyltrimethoxy silane is synthesized by selecting dimethylacrylamine and trimethoxyhydrosilane as raw materials in the presence of the catalyst and the cocatalyst, so that the synthesis process can overcome the problems of insecurity in use, storage and transportation of dimethylamine and the like, and can be used for synthesizing the N, N-dimethyl-3-aminopropyltrimethoxysilane in the presence of the catalyst and the cocatalyst. The production reaction is prevented from being carried out under a high-pressure condition, so that energy waste is avoided; the reaction conditions are mild and pollution-free, no hydrochloride is generated, and the whole production and preparation process is simple and easy to control; and in addition, a novel synthesis process is designed, the yield of the prepared N, N-dimethyl-3-aminopropyltrimethoxysilane product is 90% or above, the product purity reaches 99%, and therefore the N, N-dimethyl-3-aminopropyltrimethoxysilane has a certain application prospect in the field of silane coupling agent production and manufacturing.
